PRINTING APPARATUS.

Application filed March 4, 1915.

To all whom it may concern Be it known that I, ROBERT T. YINGER, acitizen of the United States, and a resident of Swissvale, in the countyof Allegheny and State of Pennsylvania, have invented a new and usefulImprovement in Printing Apparatus, of which the following is aspecification.

My invention relates to printing apparatus and particularly to devicesfor printing series of characters in non-rectilinearrelation, and it hasspecial reference to such devices as are adapted to apply characters toinstrument dials and the like. i

The object of my invention is to provide a device of the above-indicatedcharacter which shall be simple and durable in construction, eflicientin operation and capable of printing series of characters which may bewidely varied in number and relative position. i

More particularly, the object of my invention is to provide a device forprinting characters upon dials for meters, clocks and other instrumentswhich shall embody means for supporting a plurality of separate typeholders in non-rectilinear relative relation, together with means foradjusting the several type holders in a plurality of directions, wherebydials of many styles and sizes may be printed by means of asingledevice.

In the accompanying drawing, Figure 1 is a front elevational view, withparts shown in section, of a printing device constructed in accordancewith my invention. Fig. 2 is a side elevational view, with parts shownin section. of the device shown in Fig. 1, and Fig. 3 is a frontelevational view of a modified form of the device.

The dials of electrical measuring instruments, such as volt meters,amm'eters and the like. are commonly provided with indicating numeralsarranged in a curve which may either be a small arc of a circle ornearly a complete circle. It has heretofore been customary to provide aseparate printing form for each size and style of dial, and, since suchinstruments are made in a large number of styles and also in a greatvariety of sizes. a complete equipment for printing them has heretoforebeen both expensive and inconvenient. j Y

able type holders which may be readily adjusted-to print characters uponcurves of widely varying angular magnitude and degree of curvature. Itconsists essentially of a curved or circular frame adapted to be lockedin an ordinary printing chase and provided with radially adjustable typeholders which may also be laterally adjusted in a slot provided in theframe.

Referring to Figs. 1 and 2 of the drawing, the device thereinshownconsists of a substantially circular frame 1 which may be- Themembers 4, 5 and 6 together constitute a rectangular extension of therings 2- and 3, this extension being useful in locking the device in aprinting form or chase, the usual furniture being employed.

Disposed in the slot 8 between the rings 52 and 3 are screw-threadedpins 9 which are preferably flattened on opposite sides in order topreventthem from rotating in the slot 8. Secured to the outer end ofeach of the pins 9 is a type holder which may comprise a U-shaped frame10 adapted to receive types 11 and spacing slugs 12, the types and slugsbeing maintained rigidly in the type holders by means of screws 13.-Nuts'14 are applied to the pins 9 in order to secure the pins and thetype holders in.

any adjusted positions in the slot 8. Any desired number of thetype-holding devices may be employed. depending upon the style ofimpression to be printed and the size of the frame 1. In order to adjustthe positions of the type holders radially as well as laterally in theslots 8, spacing washers 15 may be interposed between the U-shapedmembers 10 and the rings 2 and 3, as shown at the left of Fig. 1. Thepermissible length of the pins 9. and the consequent range through whichsuch radial adjustment may be effected, are limited only by the diameterof the rings 2 and 3.

, The modified device shown in Fig. 3 differs from thatshown in Figs. 1and 2 in that the frame 20 which supports the type holders issubstantially semi-circular and has no supporting projection such as theprojection 5 shown in the first modification. The frame 20 is providedwith a slot whlch may conveniently extend from the line 21 to the line22, as shown in Fig. 3, and may be composed of two similar half ringsseparated at their ends by spacing blocks, one of which is shown at 23.

Instead of being composed of separate rings or half rings separated byspacing blocks. the type-holding fran'ie may be made of a single pieceof metal having the necessary slot cut laterally through it. If the formof frame shown in Figs. 1 and 2 is so made of one piece of metal. therectangular projection 5 may also be formed integral with the frame.

It will be evident that the form member which I have shown and describedis capable of printing impressions composed of many different numbersand arrangements of characters. and it will also be evident that mydevice may be variously modified in. its structural details andproportions without departing from the spirit and scope of my invention.It is therefore to be understood that my invention comprehends all suchmodifications as fall within the scope of the appended claims.

I claim as my invention:

1. A form member for printing series of characters comprising a frame. atype holder carried by the frame and adjustable. both radially andcircumferentially, with respect to the frame and means for securing thetype holder in adjusted position.

9. A form member for printing series of characters comprising an arcuateframe. and a plurality of type holders carried by the frame andindependently adjustable. both radially and circumferentially. withrespect to the frame.

3. A plane-printing form member for printing apparatus comprising aframe provided with a slot having walls substantially parallel to theprinting plane of the form member. and a tvpe holder secured in the saidslot and adjustable in a plurality of directions therein.

4. A plane-printing form member for printing series of characterscomprising a frame provided with a slot having walls substantiallyparallel to the printing plane of the form member. and a plurality oftype holders secured in the said slot and adjust able in a plurality ofdirections therein.

5. A plane-printing form member for printing series of characterscomprising a curved frame provided with a slot extending transversely tothe axis of the said frame and having walls substantially parallel tothe printing plane of the form member. and a plurality of type holderssecured in the said slot and adjustable both radially and lengthwise ofthe said slot.

6. A form member for printing series of characters comprising a curvedframe provided with a slot extending transversely' to the axis of thesaid frame, a plurality of flattened screw-threaded pins disposed in thesaid slot. type holders attached to the outer ends of the said pins. andmeans for secur mg the said pins in radially and circumferentiallyadjusted positions in the said frame.

7. A form member for printing series of characters comprising asubstantially semicircular frame provided with a slot extendingtransversely to the axis of the said frame. a plurality of pins disposedin the said slot. type holders attached to the ends of the said pins.and means for securing the said pins in adjusted positions in the saidframe.

8. A form member for printing series of characters comprising asubstantially circular frame provided with a slot eivtendingtransversely to the axis of the said frame. a plurality of pins disposedin the said slot, type-holders attached to the said pins, and means forsecuring the said pins in radially and circumferentially adjustedpositions in the said frame.

9. A form member for priming series of characters comprising asubstantially circular frame provided with a slot eXtending nearlyaround the said frame. a plurality of flattened pins disposed in thesaid slot, type holders secured to the outer ends of the said pins. andmeans for securing the said pins in radially and cireumferentiallyadjusted positions in the said frame.

10. form member for printing series of characters comprising asubstantially circular frame provided with a rectangular projection andalso provided with a slot eX- tending nearly around the said frame, aplurality of flattened screw-threaded pins disposed in the said slots,type, holders secured to the outer ends of the said pins, spacingwashers interposed between the said type holders and the said frame, andnuts disposed on the said pins Within the said frame for securing the.said type. holders in adjusted positions.
